Do you know the Development Process of ERW Steel

ERW Steel Pipe is the warm rolled coil plate created by the forming equipment, making use of the skin effect and also distance effect of high frequency existing to warm as well as thaw the edge of television blank, and pressure welding under the activity of the squeeze roller To accomplish production. The high-frequency resistance welding technique was related to the manufacturing of welded pipelines in the Do you need HFW for ERW steel pipe?Do you need HFW for ERW steel pipe?HFW is required in API 5L PSL2 ERW steel pipe. According the API 5L and ISO 3183 specification, for PSL 2 pipes in welded process the HFW welding is a mandatory requirements for ERW steel pipes. As it is an improvement from the inherent problems of hardness, lack of fusion and susceptibility of stress corrosion cracking (SCC).Differences between ERW Steel Pipe and HFW Steel Pipe How are electric resistance welded steel pipes formed?How are electric resistance welded steel pipes formed?ERW steel pipe is formed by rolling plate and welding the seam. Standard Specification for Electric-Resistance-Welded Carbon Steel and Carbon-Manganese Steel Boiler and Superheater Tubes ASTM A178 standard referes to electric-resistance-welded tubes with minimum-wall-thickness.Electric Resistance Welded Pipe, ERW Steel Pipes, Electric Resistance The Development Process of ERW Steel Pipe at Home and

Why are ERW steel pipe used in oil and gas industry?Why are ERW steel pipe used in oil and gas industry?ERW steel pipe used for transporting gas and liquid objects such as oil and gas, could meet the low and high pressure requirement. In recent years, with the development of ERW technology, more and more ERW steel pipe used in the oil and gas fields, automobile industry and so on. High efficiency, low cost, material saving, easy automation.Differences between ERW Steel Pipe and HFW Steel PipeChina The development history of ERW steel pipes at home The Development Process of ERW Steel Pipe at Home and

Secondly, the computers automatic control is realized in the production process of large and medium-caliber ERW steel pipe forming welding heat treatment, and the computers automatic compensation system effectively controls the heat input energy in the high-frequency welding process; preventing the welding heat input energy from being low due to high heat Input energy causes cold welding, false Development process was established in 2012, headquartered in Shaanxi.The company is a production, research and development, sales as one of the modern enterprises, has a strong technical force and self - export capacity.
